Roughneck Training-Part 3: Making A Trip (DVD)

After making hole for a little while, it’s time to change the bit and make a trip, or taking all of the drill string out of the hole, standing it in the derrick, changing the bit, and putting the drill string back in the hole. This requires all crew members on a rig to be present, safe, and efficient. This training film points out factors rotary helpers should consider to make a round trip in a proper and safe manner. 1983, 18 minutes. Comes with a workbook.
